Answer 1

To find the value of x, we need to isolate the variable on one side of the equation by performing the inverse operations.

Starting with the given equation:
-2x + 902 = 1518

Subtracting 902 from both sides:
-2x = 616

Dividing both sides by -2:
x = -308

Therefore, the best estimate for x is -300.
